GLOBE-VALVE.

SPECIFICATION forming part of Letters Patent N 0. 530,478, dated December 4, 1894.

Application filed May 24, 1894. 1

To a. wh om, it may concern.-

Be itknown that I, HENRY R. FRISBIE, a citi; zen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certainnew and useful Improvements in Globe-Valves, of which the following is a specification.

My invention relates to certain new and useful improvementsin valves, the object and nature of which will be more fully described in the following specification and such features as I believe to be new and novel particularly pointed out in the claims.

To enable others to understand my invention, reference is had to the accompanying drawings, in which i Figure 1 represents a central vertical section of the valve, its seat and valve disk. Fig. 2 is a detail view, partly in section of the valve bonnet through line ct, bonnet and spindle through line b; and diaphragm supporting the valve seat through lines a, d, of Fig. 1; which view also represents the valve raised from its seat. Fig. 3, is an enlarged detail sectional view of the valve-disk carrier, valve disk, retaining cap therefor, broken view of the valve spindle and guide for the disk carrier. Fig. 4 is a detail side elevation of the valve-disk carrier. Fig. 5 is a detail upper plan view of the valve disk carrier, looking in the direction of arrow d, Fig. 4..

Fig. 6 is a detail bottom plan of the disk-carrier, looking in the direction of arrow c, Fig. 4. Fig. 7 is a detail plan view of the disk-retaining cap, looking in the direction of arrow f, Fig. 8. Fig. 8 is a detailside elevation of the disk-retaining cap. Fig. 9 is a detail upper plan of the stuffing box end of the valve bonnet, looking in the direction of arrow g, Fig. 1. Fig. 10 is a broken sectional view of the upper end of the valve bonnet, through line b, of Fig. 1. A

Its construction and operation are as follows: 1 represents the valve body; 2, the valve bonnet; 3, packing chamber in .the upper end thereof. The sides h of this packing chamber are inclined at an angle of sixty degrees toward the guide bearing dfor the valve spindle 4., Figs. 1 and 10. This inclination of the sides of this packing chamber will cause Serial No. 512,266- (No model.)

plished by the slightest movement of the packing nut 5. To prevent the packing placed in said chamber from turning when either the spindle {l or the nut 5 are rotated, I prefer to cut the channels 6 (see also Fig. 9) in the inclined sides h of the packing chamber wherein the packing will be forced for this purpose.

The disk-carrier 7, see Figs. 1, 2, 3, 4. and 5, is arranged to be mounted on the lower end j of the valve'spindle 4.,for which the lateral jopening I is formed in the side of said carrier. The upper end of said carrier is provided with the enlarged bore m which operatively engages the downward projecting support and guide 9of the valve'bonnet 2. The opening it extends to the topof said carrier and opens into the enlarged bore m to admit the body portion of the valve spindle, so that, when the said spindle is inserted therein and the carrier engaged with its supporting guide, said carrier is effectually locked thereto, but, nevertheless, it is allowed an independent rotary movement on the spindle and its valve disk 10, which it carries, is made to assume different positions on the valve seat 11, thus preventing an uneven wearing of their meet,-

ing faces, which would result from a vertical movement only.

The interchangeable valve disk 10 (see Fig. 3) ispreferably made of copper or other semihard material whose inclined sides engage the inclined face of thevalve seat 11, Figs. 1 and 2. This disk is in the form of a frustum of a cone, whose outer inclined sides fit a correspondingly shaped recess in the bottom of the carrier 7. A large central hole in said disk fits over the central concentric boss 12 of said carrier. The central portion of this .boss is furnished with the square recess 13 (see also Fig. '6) to receive the square projection 14. (Figs. 7 and 8) of the disk-retaining cap 15. This cap is provided with the cen- 95 tral threaded hole 16 to receive the threaded end of the screw 17 of Fig. 3, presently to be more fully described.

To attach the disk 10 to the carrier, it is inserted into the recess in the lower end thereof, before mentioned, and the square end or projection 14 of the cap 15 is forced into the square recess 13 of said carrier. The retaining screw 17 is then inserted from above through the enlarged bore m and firmly screwed into. said retaining cap, so that when the spindle head j is introduced into the recess k of said carrier the screw is effectually locked, which feature, combined with the engagement of the squared portions 13 and 14 respectively of the carrier and cap, will also effectually lock the disk to said carrier and thereby prevent accidental displacement therefrom, which often occurs from the constant engagement and disengagement of the disk with its seat.

To unlock or disengage the disk carrier, the bonnet is simply unscrewed from the body and removed therefrom, and the'carrier run down by the valve spindle until it leaves said guide, when it can be slipped laterally from said spindle and if necessary, the valve-disk can then also be easily removed.

The combined features, viz: of the disk-carrier and guide therefor, and the ease with which it may be locked thereto and unlocked therefrom, the frustum-shaped valve-disk and'its correspondingly shaped seat in the end of the carrier, whereby it is firmly supported against the vertical pressure of the spindle, the locking feature of its retaining cap, all combined, make a cheap and durable valve whose parts are easily interchangeable or replaced, as occasion may require.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a valve of the character described, with the body 1, bonnet 2, valve spindle 4, round projecting disk-carrier supporting guide 9, of the disk-carrier 7 hav ing bore m to engage with such support as shown, said carrier having lateral opening is to admit both the body of said spindle and the head portion j thereof, a frustum shaped valve disk, frustum-shaped seat in the end of said carrier for said disk, wherebyit is firmly supported therein, disk-retaining cap 15 hav ing the square projection 14 thereon arranged to fit a square recess in the end of said carrier, retaining screw 17 engaging said cap from above, so that when the valve spindle isattached to said carrier said screw is prevented from turning, as set forth.

2. The herein described improvement in valves, comprising in combination, a valvedisk carrier and a detachable disk, a retaining screw for securing said disk to its carrier, a valve spindle for operating said carrier, the lower end of said spindle abutting the head of said retaining screw so as to effectually lock it against displacement, and means to eifectually lock the said disk against rotation, for the purpose set forth.

Signed at Newark, in the county of Essex and State of New Jersey, this 23d day of April, A. D. 1894.
